EBPECIFICATION forming part o f Letters Patent No. 312,225, dated February 10, 1885.

Application led July E26, 1884. (No morlcl.)

To a/ZZ whom t may concern,.-

Be it known that I, CHARLES SUTTON, of the city and county of San Francisco, and State of California, have invented an Improvement in Dies for Stamping Margins for Cement- Work; and I hereby declare the following to bea full, clear, and exact description thereof.

My invention relates to a new and useful die for stamping margins in order to imitate what is known as chisel-work77 in natural stone; and my invention consistsin the peculiar formation of a die which will be hereinafter described and claimed.

Referring to the accompanying drawings, Figure l is a view of a portion of cementwork properly margined or bordered. Fig. 2 is a view of a single stamp provided with parallel ribs and a dividing or return edge, whereby a single margin may be formed of a character usually seen in chisel-work. Fig. 3 is a view of a stamp similar in character to that shown in Fig. 2, but double.

It has been customary heretofore to simply divide the blocks of cement-work by means of a suitable tool, which by being drawn along the yet unhardened cement cuts into it, and to make no margin or border whatever onthe block. In some instances, however, a line parallel to the dividing-line has been made by a trowel in similar manner, which is supposed to indicate a border; but both in the manner of its formation and the character of the border thus formed it differs from my invent-ion in that mine is formed by stamping directly, and not byadraw-cut, and I propose to make a border in imitation of such as are usually made by chisel-work in the natural stone. After the cement is laid, and while still unset, I take a stamp, A, similar to those shown, and press it down into the cement. The sharp projecting edge c of the stamp forms the division or return edge, pressing the cement into more compact form, thus preventing the tendency to crumble. The ribs a sink into the cement and produce a corrugated or roughened surface, as shown in Fig. l, which represents perfectly the usual chiselwork in natural stone. This margin or bordery is thus rapidly and effectively formed, andin the case of sidewalks is advantageous in preventing slipping. For cement-work in build ing operations I may use various kinds of dies provided with suitable designs represent1 ingchisel-work. By thusstampingtheborder I am enabled to prepare large stones which v could not be cast, and which would otherwise have to be chiseled out by hand at much labor and expense.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-` A device for stamping margins or borders in cement-work, consisting ot' a die, A, provided With a division edge or blade, with corrugations upon one or both sides of the di vision-edge, and a suitable handle, substantially as herein described.

Y In witness whereof I have hereunto set my hand.

CHARLES SUTTON.
